Shani Davis wanted to end his Olympic career with a flourish. Instead, one of America's greatest speedskaters endured a miserable time with the rest of his U.S. teammates at the Sochi Games.

For the first time since 1984, the Americans failed to win any medals in 12 events at the oval, leaving Davis pondering his future in the sport he's loved since he first started skating as a 6-year-old in his hometown of Chicago.

"We came in being one of the most decorated disciplines in the Winter Olympics and we come away with zero medals," he said. "It's horrible."

Davis wasn't at Adler Arena on Saturday when the U.S. men finished seventh in team pursuit, the final speedskating event of the games. He skated in Friday's quarterfinal loss, but was replaced by alternate Joey Mantia for the D final. Mantia, Brian Hansen and Jonathan Kuck finished seventh among eight teams.

In the women's pursuit, Brittany Bowe, Heather Richardson and Jilleanne Rookard were sixth, the highest U.S. showing in speedskating in Sochi.

Davis finished eighth in the 1,000 meters, where he was the two-time defending champion. He was 11th in the 1,500, having won silver medals at the previous two Olympics. He finished 24th in the 500, using the event as a warm-up for his two strongest distances.

"It leaves a bitter taste in my mouth knowing that I put a lot of work into it and I didn't get anything out of it," he said.

Davis put the blame for his poor results squarely on himself.

"It was a lot of things going on around me, but I've dealt with worse and I've performed under those circumstances, so there's really no excuse not to be able to perform here," he said. "I can do a better job with probably eliminating some of those things that stress me out and take away from me being able to perform."
